| dc.description |
Osseointegrated implants have been used to improve denture support, stability and retention. Currently, the placement of 2 implants and the fabrication of an implantretained overdenture is considered by some to be the standard of care. The influence of various types of attachments on stress distribution of 2-implant-retained mandibular overdenture designs has not been sufficiently assessed. The purpose of this study was to compare the load transfer characteristics of 5 attachment systems for 2-implant-retained mandibular overdenture designs. One photoelastic model was fabricated having 2 screw-type implants (3.75 X 13 mm) embedded in the interforaminal region and implants were parallel to each other and vertically oriented. Five retention mechanisms were studied on model; a bar with yellowcolored clips, a milled galvanoformed bar, a bar with two clear distal locator attachments, a bar with two distal ceka attachments, clear locator attachments. For measurements of stress a vertical load 135 N was applied unilaterally to the central fossa of the right first molar. The resultant stresses that developed in the supporting structure were monitored photoelastically and recorded photographically. A bar with two clear distal locator attachments and,clear locator attachments showed higher stress than other attachments |
